Job description

The Basics:

We are looking for a Senior Stock Administrator to support the day-to-day operation of our global equity compensation program. This person will help manage the full lifecycle of RSU awards, from issuance through vesting and release, maintain cap table accuracy, and support the financial reporting and audit work tied to equity. You'll work closely with Payroll, Legal, HR/Benefits, and our stock plan platform provider. This is a hands-on role suited to someone who has run equity operations at scale, is comfortable owning process rather than just executing tasks, and knows how to use AI tools to make equity operations faster and more accurate.

This position follows the Company’s hybrid schedule which currently requires employees to work in the office at one of the following locations a minimum of three days per week: Addison, TX; Bellevue, WA; Durham, NC; Emeryville, CA; or Reston, VA.

What you’ll do:

• Administer day-to-day global equity operations, including new grant setup, RSU vesting and releases, terminations, and grant cancellations

• Maintain accurate grant and vesting data in the stock plan platform (e.g., Shareworks) and reconcile against internal systems

• Oversee cap table management and ensure data accuracy across the platform, HRIS, and internal trackers

• Assist with tax withholding and reporting for equity events, working with Payroll to confirm accuracy

• Ensure compliance with applicable equity and securities regulations and internal governance requirements

• Support financial reporting requirements related to equity, including preparing and reviewing equity-related disclosures for audits and filings

• Respond to employee questions about their equity awards, vesting dates, and tax withholding

• Prepare recurring and ad hoc reports for Finance, Payroll, Legal, and leadership

• Support internal controls and audit requests related to equity administration

• Assist with IPO readiness projects, including equity data cleanup, cap table validation, system analysis and process documentation

• Use AI tools to build and improve equity administration processes, such as ticket handling, employee inquiry responses, and vesting tracking, and document these processes clearly for the team

We’re looking for someone with:

• Bachelor's degree in Finance, Accounting, Business, or a related field

• 3-4+ years of experience in stock plan administration, including RSU processing

• Experience at a publicly traded company is strongly preferred, given the higher bar for reporting accuracy, SEC-related deadlines, and audit readiness in that environment

• Strong knowledge of equity compensation regulations and tax implications

• Working knowledge of equity administration platforms (Shareworks, Equity Edge Online, or similar)

• Solid understanding of RSU mechanics: cliff vesting, tranche-based vesting, vesting pauses, and adjusted vest dates

• Practical experience using AI tools (e.g., for drafting communications, building trackers, or automating routine tasks) to improve accuracy and speed in an operational role

• Advanced Excel and data management skills; comfort building and maintaining tracking tools

• High attention to detail and strong analytical ability, with a track record of catching discrepancies before they become problems

• Ability to handle confidential compensation data with discretion

• Clear written and verbal communication, including explaining equity concepts to non-experts and coordinating across Finance, Legal, HR, and Payroll

Nice to have:

• CEP Level II or III candidate or CEP (Certified Equity Professional) designation

• Experience with a company transitioning from private to public, or vice versa

• Familiarity with global equity plans and cross-border compliance

• Strong stakeholder management skills across Finance, Legal, HR, and Payroll
